Abstract: A recording device which improves a response time to write data by reporting to a host computer the completion of writing operation prior to the completion of writing redundancy data. Data writing command information from the host computer is stored in a command/status memory backed up by a power source in an array controller, and the completion of writing operation is reported to the host computer at the time of the completion of writing updated data prior to the completion of writing redundancy data. Redundancy data is written as a background process. If redundancy data could not be written due to any abnormality of the power source or the like, such redundancy data may be generated from the data in other disk units of the same redundancy group in accordance with writing command information stored in the command/status memory, thereby completing the writing of redundancy data.

Abstract: A B₂O₃-doped tubular porous silica preform is heated, and a fluorine-containing gas, such as SiF₄ or CF₄, is flowed into its aperture. The temperature is sufficiently high to cause the fluorine-containing gas to decompose and form fluorine which dopes the preform. Also flowed into the aperture is a sufficient amount of BF₃ to prevent fluorine from reacting with the B₂O₃ in the porous preform and thereby inhibit formation of a B₂O₃-depleted region near the aperture surface. 
     The doped porous preform is then consolidated to fuse the particles and form a dense glass tube containing both boron and fluorine as dopants with substantially uniform radial composition profiles (see fig.5). Optical fibres can be placed in the dense glass tube which is then collapsed to form a fibre optic coupler.

Abstract: A method for the maintenance of a high temperature reactor is described, in which a lower hearth part which is damaged as a consequence of mechanical, chemical and/or thermal stress and forms a structural unit with a molten bath hearth is exchanged for a back-up unit. Charging of the high-temperature reactor is firstly interrupted for this purpose. The molten liquid is withdrawn from the molten bath in the lower hearth part. The combined fuel burners, which are lead via cooling jackets through the hearth wall, are removed, and the connecting elements between the upper part and hearth part are loosened. The hot lower part is then removed from its operating position. The back-up unit, which has been heated in advance, is brought into the operating position, and the combined fuel burner is introduced together with the oxygen leads into the cooling jackets of the back-up unit. <IMAGE>

Abstract: A coin storage structure includes a partition plate, a coin storage window, a shielding plate, and a link mechanism. The partition plate vertically partitions a housing into a processing chamber for storing a coin processing unit and a safe chamber for storing a safe. The coin storage window is formed in the partition plate to cause a coin discharged from the coin processing unit to drop into the safe in the safe chamber, thereby storing the coin. The shielding plate selectively opens and closes the coin storage window. The link mechanism removes the shielding plate from the coin storage window in a state that at least the door of the processing chamber is kept closed, and causes the shielding plate to face the coin storage window to shield the coin storage window in synchronism with an opening operation of the door.

Abstract: A shaft (44,144,145) is conventionally driveably connected to a bore (46,146) by a steel key of rectangular cross-section. Where the shaft is of smaller diameter than the bore, a slotted nylon sleeve is fitted between them and a tall steel key extends through the slot. Failure of both standard and tall keys can occur for various reasons. A unitary component (50,162,163) of suitable plastics material or non-ferrous metal is therefore proposed. This component essentially includes an integral key (56,174) of curved cross-section adapted to engage in a mating keyway (176) formed in the bore. Where the shaft (44) and bore (46) are nominally of the same diameter, the component (50) consists also of an integral key (52) of rectangular cross-section adapted to engage in the conventional keyway (48) in the shaft. Where the shaft (144,145) is of smaller diameter than the bore (146), the component (162,163) also includes a sleeve (164) with the key (174) of curved cross-section formed on its outer periphery, and a keyway (170) of rectangular cross-section formed in its inner periphery and adapted to be driveably connected by a separate standard key (171) to the conventional keyway (148,149) in the shaft. The component is useful in the flange-mounting of different electric motors on off-the-shelf gear units.

Abstract: High addressability image signals (8), each representing a pixel in an image, where the signal has one of a relatively large number of signal levels, are directed through an error diffusion quantization process, for the conversion of the signal to one of a relatively small number of levels. Each signal (I n,ℓ ) is modified (10) by a correspondingly weighted error correction term signal or signals (ε n,ℓ ) from previously processed image signals, thereby generating (12) a modified image signal (I n,ℓ  + ε n,ℓ ). This modified image signal is compared (14) to a threshold to derive a preliminary output signal (B' n,ℓ ) having a smaller number of levels. The preliminary output signal is directed (42) to an output (16) if it has the same level as the previous output signal. If the preliminary output signal does not have the same level as the previous output signal, the preliminary output signal is directed to the output only if the previous output signal was one of a contiguous group of a preselected number of like level signals. Otherwise, the previous output value is directed to the output. The actual output signal (B n,ℓ ) is then compared (22) to the modified input signal (I n,ℓ  + ε n,ℓ ) to derive an error signal (ε n,ℓ ) for the diffusion feedback loop that maintains gray density.

Abstract: An atrial defibrillator (30) reliably detects a depolarization activation wave of the heart and delivers cardioverting electrical energy to the atria of the heart in synchronism with a detected depolarization activation wave. The atrial defibrillator includes a first sensor (53,52) for producing a first electrical output having a duration substantially equal to the duration of the depolarization activation wave sensed between a first pair of spaced apart locations (38a,40a) of the heart. The atrial defibrillator further includes a second sensor for producing a second electrical output having a duration substantially equal to the duration of the depolarization activation wave sensed between a second pair of spaced apart locations of the heart. The spacing between the second pair of locations is greater than the spacing between the first pair of locations. A microprocessor (60) is responsive to the first and second electrical outputs for providing an indication signal indicating the occurrence of the depolarization activation wave when the second electrical output is longer in duration than the first electrical output. A pulse generator (66) coupled to the microprocessor applies electrical cardioverting energy to the atria of the heart in response to the indication signal.

Abstract: 2.1 To improve the audio signal transmission, audio signals are additionally recorded and scanned in accordance with the hifi depth-division multiplex method in addition to the video signal on the helical tracks in home video recorders. Additional rotating heads record the audio signal in the depth of the magnetic layer and the video heads write the video signal on the surface of the tape. The invention makes it possible to omit these additional heads and electronic and mechanical accessories, improves the crosstalk characteristic, avoids head changing problems and ensures full compatibility with the existing system. 2.2 This is made possible in that the video heads are additionally supplied with at least one audio carrier signal which is intermittently modulated with samples of the audio signals during the horizontal blanking in addition to the composite FM signal and converted chrominance signal. 2.3 The video recorder provides for hifi stereo operation in home video recorders, especially also at reduced tape speed. <IMAGE>
